The increasing interest in the development of identification methods of explosives in THz region over the past few years has been observed because of potential terrorist threats. To determine specific spectra properties of materials both possible spectroscopic methods - time domain spectroscopy and Fourier transform infrared spectroscopy are used to analyze different classes of compounds. This paper deals with an identification problem of more than one compound. This task was solved mathematically by means of the following methods: Monte Carlo including principal components analysis methods and analytic methods. Investigations were limited to a detector, which based on a single-frequency quantum dot matrix in 0.3 ÷ 1.3 THz range. The mathematical analysis also includes the atmosphere influence on propagation of THz waves. By means of the presented methods we indicated fourteen optimal frequency points and next we managed to identify one explosive from a set of ten explosives.
